The car comes standard with passive dampers, just like the E90. If you get the sports suspension, it's the exact same but the car is a little lower.

Adaptive M suspension allows you to choose different levels of suspension stiffness in the different modes (Comfort, Normal, Sport) and I think it is adaptive within those modes like the E9x M3's EDC but I'm not entirely sure.

Drop is the same (confirmed w/ head office). Both are 10mm lower than stock suspension.
